What's active right now

Lone-star ticks are at their summer peak, the main local driver of alpha-gal syndrome and ehrlichiosis. Midsummer is when lone-star bite counts run highest region-wide. Gulf Coast tick adults are active in the same brushy, grassy habitat. American dog ticks are also out in open, grassy areas. Deer ticks remain a minor factor here compared with the Northeast.

Local tick habitat

Callahan is 78% natural land cover (63% forest, plus open and brushy areas) across its 1.81 sq mi, home to about 1,798 people. That makes it the 3rd-most wooded of the 3 towns in Nassau County. Lone-star and Gulf Coast ticks favor brushy edges, overgrown fields, and open pine woods as much as deep forest: the more of that a town has, the more places ticks can quest.

Nassau County's CDC Lyme rate is negligible, unsurprising this far south, so deer ticks are a minor factor in Callahan. The lone star tick is what actually drives local risk here: it is established region-wide, bites aggressively at every life stage, and is the tick most responsible for alpha-gal syndrome, ehrlichiosis, and STARI in Florida.

Tick control in Callahan, FL

Do I need tick control in Callahan?

Tick activity in Callahan is moderate today (36/100). Ticks are out, especially along yard edges, leaf litter, and shady borders. A seasonal treatment plan keeps numbers down before peak weeks hit.

Professional tick control in Callahan typically means a barrier treatment along the lawn edge, leaf litter, stone walls, and shady borders where ticks wait for a host, applied two to four times a season by a licensed pest control company. It is the single most effective way to cut tick numbers in the part of the yard your family actually uses.

How much does tick control cost in Callahan?

Most homeowners pay about $100 to $200 per visit for professional tick spraying, or roughly $350 to $600 for a full season of barrier treatments, depending on lot size and how wooded the property is. Quotes are free, so it costs nothing to get a real number for your yard.

Does Callahan have lone star ticks that cause alpha-gal syndrome?

Yes. The lone star tick is established in Nassau County and is the tick most responsible for human bites in Florida. Its bite can trigger alpha-gal syndrome, a delayed allergy to red meat and other mammal products, along with ehrlichiosis and STARI. Unlike the Northeast, Lyme disease is a minor factor here: the lone star tick, not the deer tick, is what actually drives local risk. Learn the symptoms and what foods to avoid.
